  2. Foot–pound–second system of units - Wikipedia

    en.wikipedia.org/wiki/Foot–pound–second...

    The technical or gravitational FPS system [6] or British gravitational system is a coherent variant of the FPS system that is most common among engineers in the United States. It takes the pound-force as a fundamental unit of force instead of the pound as a fundamental unit of mass. In this sub-system, the unit of mass is a derived unit known ...

  3. Foot per second - Wikipedia

    en.wikipedia.org/wiki/Foot_per_second

    The foot per second (plural feet per second) is a unit of both speed (scalar) and velocity (vector quantity, which includes direction). [1] It expresses the distance in feet (ft) traveled or displaced, divided by the time in seconds (s). [2] The corresponding unit in the International System of Units (SI) is the meter per second.

  4. Poundal - Wikipedia

    en.wikipedia.org/wiki/Poundal

    Since a pound of force (pound force) accelerates a pound of mass at 32.174 049 ft/s 2 (9.80665 m/s 2; the acceleration of gravity, g), we can scale down the unit of force to compensate, giving us one that accelerates 1 pound mass at 1 ft/s 2 rather than at 32.174 049 ft/s 2; and that is the poundal, which is approximately 1 ⁄ 32 pound force.

  5. Imperial and US customary measurement systems - Wikipedia

    en.wikipedia.org/wiki/Imperial_and_US_customary...

    The FPS unit of work is the foot-poundal. [ 53 ] Other systems for the measurement of dynamic quantities that used imperial and US customary units are the British Gravitational System (BG) proposed by Arthur Mason Worthington and the English Engineering System (EE).

  6. Work (physics) - Wikipedia

    en.wikipedia.org/wiki/Work_(physics)

    Usage of N⋅m is discouraged by the SI authority, since it can lead to confusion as to whether the quantity expressed in newton-metres is a torque measurement, or a measurement of work. [15] Another unit for work is the foot-pound, which comes from the English system of measurement. As the unit name suggests, it is the product of pounds for ...

  7. Units of energy - Wikipedia

    en.wikipedia.org/wiki/Units_of_energy

    The British imperial units and U.S. customary units for both energy and work include the foot-pound force (1.3558 J), the British thermal unit (BTU) which has various values in the region of 1055 J, the horsepower-hour (2.6845 MJ), and the gasoline gallon equivalent (about 120 MJ).

  9. Foot-pound (energy) - Wikipedia

    en.wikipedia.org/wiki/Foot-pound_(energy)

    The foot-pound force (symbol: ft⋅lbf, [1] ft⋅lb f, [2] or ft⋅lb [3]) is a unit of work or energy in the engineering and gravitational systems in United States customary and imperial units of measure. It is the energy transferred upon applying a force of one pound-force (lbf) through a linear displacement of one foot.
